32. Randomness and Secure Token Generation

The random module is not cryptographically secure. Use secrets for tokens or keys.

Insecure Example​

import random
token = random.randint(1000, 9999)
print("Insecure token:", token)

Secure Example​

import secrets
token = secrets.token_hex(16)
print("Secure token:", token)

✅ Lesson: Use secrets for any security-sensitive randomness.
